- Be it known that I, MA TIN of New Y0rk,have invented anew and u-sc ful Machine for Coating Paper, of which the following is a specification, reference being had. to the 'accomp anymg' draw ng, in which' Figure 1- shows my improved inachine inside elevation; Fig. 2'is an end elevation of the machine; and Fig. 3 ls-a side. elevation showing'a modified construction-of the apparatus.

simple manner and withgreat uniformity.

The purpose, of the-coatingis to surface the paper'pre'paratory to printing or-lithograph- An important feature of'the invention resides in a peculiar combination and arrange ment of color-applying rolls, whereby a uniform amount of color will be applied to each 1 side of the work regardless of the rate, of

speed of the machine.

I prefer to employ what will be termed hard-faced colora'p lying rolls, as distinguished from brush...

rol s, although, as a matter of fact, the rolls will be provided with yieldable surface cov. It will therefore erings, for instance, felt he understood that hereinafter where 1 use the term hard-faced roll, 1. means to. ex-
